Asymptotic symmetries and memories of gauge theories in FLRW spacetimes
Martin Enriquez-Rojo, Tobias Schroeder
In this paper, we investigate the asymptotic structure of gauge theories in decelerating and spatially flat Friedmann-Lemaître-Robertson-Walker universes. Firstly, we thoroughly ex…
Asymptotic dynamics and charges for FLRW spacetimes
Martin Enriquez-Rojo, Till Heckelbacher, Roberto Oliveri
We investigate the asymptotia of decelerating and spatially flat FLRW spacetimes at future null infinity. We find that the asymptotic algebra of diffeomorphisms can be enlarged to…
Boundary Heisenberg Algebras and Their Deformations
Martin Enriquez-Rojo, H. R. Safari
We investigate the deformations and rigidity of boundary Heisenberg-like algebras. In particular, we focus on the Heisenberg and algebras w…
On deformations and extensions of
Martin Enriquez-Rojo, Tomáš Procházka, Ivo Sachs
We investigate the algebra of vector fields on the sphere. First, we find that linear deformations of this algebra are obstructed under reasonable conditions. In particular, we sho…
Holography and black holes in asymptotically flat FLRW
Martin Enriquez-Rojo, Till Heckelbacher
In this paper, we extend the treatment of asymptotically decelerating spatially flat FLRW spacetimes initiated in [1]. We show that a certain class of those metrics is ruled by the…
Asymptotic symmetries in spatially flat FRW
Martin Enriquez-Rojo, Till Heckelbacher
We perform an off-shell treatment of asymptotically decelerating spatially flat FRW spacetimes at future null infinity. We obtain supertranslation and superrotation-like asymptotic…
Swampland conjectures for type IIB orientifolds with closed-string U(1)s
Martin Enriquez-Rojo, Erik Plauschinn
We study the weak gravity conjecture, the swampland distance conjecture and the emergence proposal for orientifold compactifications of type IIB string theory with…
